Description

Technical Field

[0001] The utility model relates to the technical field of beer or beverage bottles, in particular to a beer or beverage easy-pull bottle cap and a bottle. Background Art

[0002] In the beer (beverage) industry, bottle cap sealing is a key link in the beer (beverage) production process, which is directly related to the shelf life, freshness and consumer drinking experience of the product. Existing bottle caps include twist-off bottle caps, crown caps, and combined pull ring and cap caps (such as Tuborg beer easy-pull bottle caps), etc. However, existing bottle caps have disadvantages:

[0003] 1. The crown cap is a traditional beer or beverage bottle cap. When opening the bottle cap, it needs other tools (such as a bottle opener) to open it, which is inconvenient.

[0004] 2. The combined bottle cap of the pull ring and the cover has the pull ring arranged on the side of the cover body, vertically downward to the bottle, which not only affects the integrity and appearance of the bottle cap, but also because the bottle cap does not use a labor-saving structure, when using it, it is necessary to insert the finger into the pull ring and then pull hard to tear the side of the bottle cap. In this process, a large initial force is required before the side of the bottle cap is broken, which is more difficult for people with less strength, and the fingers will be squeezed and feel slight pain.

[0005] Therefore, the utility model provides a beer or beverage easy-pull bottle cap and a bottle using the bottle cap. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model aims to provide a beer or beverage easy-pull bottle cap to solve the problem that the existing bottle caps are difficult to open and require a lot of effort to open.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A beer or beverage easy-pull bottle cap comprises a cap body, a pull ring is statically fitted on the top surface of the cap body, a tear line is arranged on the top surface of the cap body, a connecting portion connected to a position of the top surface of the cap body close to the tear line is arranged on the inner side of the pull ring, a pushing portion is arranged on the outer side of the pull ring away from the connecting portion, and a supporting portion which can be abutted against the top surface of the cap body is arranged on the outer side of the pull ring close to the connecting portion, by pushing the pushing portion upward, the pull ring pulls up the connecting portion with the supporting portion as a fulcrum and then tears the tear line.

[0009] Principle of the utility model:

[0010] See also Figure 3As shown, in this scheme, the pull ring is a lever with the support part as the fulcrum, the push part is the power point, F2 is the power, the distance L2 between the push part and the support part is the power arm, the connection part is the resistance point, F1 is the resistance, and the distance L1 between the connection part and the support part is the resistance arm. According to the balance condition of the lever: F2L2=F1L1, the magnitude of the power and the resistance is inversely proportional to the length of the corresponding force arm. In this scheme, since the connection part is located between the push part and the support part, that is, L2>L1, in order to meet the lever balance condition, F2<F1, when opening the bottle cap, you only need to bend or push the push part upwards, bend or push the pull ring to an inclined or vertical position with the top surface of the cap body, at this time, a small hole is torn on the tear line, and then the finger is inserted into the pull ring to continue to pull it up, which is more labor-saving.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] When using this solution, after bending or pushing the push part upward, the pull ring uses the support part as a fulcrum to pull the connection part upward, and the force of the connection part pulling up acts on the tear line, breaking the tear line, and then continuing to pull the pull ring to open the bottle cap, which is convenient and labor-saving. This solution can solve the problem that traditional crown caps are difficult to open or inconvenient to open. In addition, the pull ring in this solution uses the lever principle, and the initial force of tearing the tear line is more than 5 times less. Compared with traditional combined bottle caps, it is more labor-saving to open the bottle cap, has good integrity, and beautiful appearance, which is conducive to wide promotion.

[0013] As a preferred embodiment of the present invention, a center line connecting the pushing portion and the connecting portion passes through the center of the pull ring.

[0014] Beneficial effects:

[0015] In this solution, since the center line connecting the pushing part and the connecting part passes through the center of the pull ring, it can be seen that the power point and the resistance point are distributed on both sides of the center along the diameter of the pull ring. Therefore, L2>2L1, to meet the lever balance condition, F2<1 / 2F1, it is more labor-saving when opening the bottle cap.

[0016] As a preferred embodiment of the present invention, one end of the tear line extends to the edge of the side wall of the cover body, and the other end of the tear line extends to the side wall of the cover body and is located in the middle of the side wall.

[0017] Beneficial effects:

[0018] In the present solution, one end of the tear line extends to the edge of the side wall of the cap body, which can destroy the integrity of the cap body when the bottle cap is opened, so as to remove the bottle cap and the sealing pad; the other end of the tear line only extends to the middle of the side wall of the cap body, that is, the torn part is still connected to the cap body, so that when the bottle cap is removed, the cap body can fall off together with the torn part, so as to avoid the torn part and the pull ring from being separated from the cap body, so as to facilitate overall recycling.

[0019] As a preferred embodiment of the utility model, a boss is provided on the top surface of the cover body, the boss is statically matched with the pull ring, and the upper end surface of the pull ring is flush with the top surface of the boss.

[0020] Beneficial effects:

[0021] The boss and the pull ring in this solution are statically matched, which can restrain the pull ring from easily tilting up under a certain external force, thereby preventing the bottle cap from being accidentally opened during handling or transportation, resulting in sealing failure. In addition, the upper end surface of the pull ring is flush with the top surface of the boss, which can make the top surface of the bottle cap smoother, better in integrity, and more beautiful.

[0022] As a preferred embodiment of the present invention, a first curved plate that cooperates with the side wall of the boss extends downward from the inner side wall of the pull ring.

[0023] Beneficial effects:

[0024] The first curved plate in this solution can increase the contact area with the side wall of the boss, increase the static fit surface, and improve the static fit effect; at the same time, since the pull ring acts as a lever, the first curved plate can play the role of a reinforcing rib to increase the force strength of the lever, making it more stable when opening the bottle cap.

[0025] As a preferred embodiment of the present invention, the connection portion is provided with a rivet hole, and a rivet is integrally stamped and formed on the top surface of the cover body to match the rivet hole, and the connection portion is riveted to the top surface of the cover body.

[0026] Beneficial effects:

[0027] The rivets in this solution are formed by integral stamping, so that the integrity of the cover body is better, and the processing is convenient and the material utilization rate is high.

[0028] As a preferred embodiment of the utility model, the outer side wall of the pull ring extends downwardly with a second curved plate except for the push portion, the lower end surface of the second curved plate abuts against the top surface of the cover body, and the outer side wall of the second curved plate is flush with the side wall of the cover body.

[0029] Beneficial effects:

[0030] The second curved plate provided in the present solution is abutted against the top surface of the cover body, which can improve the stability of the pull ring on the top surface of the cover body and further enhance the strength of the lever.

[0031] As a preferred embodiment of the utility model, the pushing portion exceeds the edge of the cover body, and a space is formed between the lower side of the pushing portion, the second curved plate and the top surface of the cover body.

DETAILED DESCRIPTION

[0042] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0043] In the description of the present application, the terms "top", "bottom", "one end", "one side", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0044] See also Figure 1 and Figure 2As shown, this embodiment discloses a beer or beverage easy-pull bottle cap, including a cover body 1, a pull ring 2 and a sealing pad 3. The sealing pad 3 is assembled in the cover body 1 and is used to seal the bottle mouth. The cover body 1 and the pull ring 2 are both sheet metal parts. The pull ring 2 is statically matched with the top surface of the cover body 1. Specifically, a boss 11 is integrally formed on the top surface of the cover body 1. The boss 11 is statically matched with the pull ring 2 (static fit is the old name of interference fit), and the upper end surface of the pull ring 2 is flush with the top surface of the boss 11. The inner side wall of the pull ring 2 is integrally extended downward with a first curved plate 24 that is matched with the side wall of the boss 11. The first curved plate 24 is matched with the side wall of the boss 11 to increase the static fit surface, improve the static fit effect, and then constrain the pull ring 2 to prevent the pull ring 2 from easily tilting up under a certain external force, resulting in sealing failure.

[0045] The top surface of the cover body 1 is provided with a tear line 12, see Figure 4 As shown, the tear line 12 includes an arc segment arranged on the boss 11, and two curved segments extending from both ends of the arc segment to the side wall of the cover body 1, wherein the end point of one curved segment extends to the edge of the side wall of the cover body 1, and the end point of the other curved segment extends to the middle of the side wall of the cover body 1, and the area enclosed by the two curved segments and the arc segment is the tear area. A connecting portion 21 extending inward is integrally formed on the inner side of the pull ring 2, and a rivet hole 211 is opened in the center of the connecting portion 21. A rivet 111 is integrally stamped and formed in the tear area near the tear line 12 to match the rivet hole 211, and the connecting portion 21 is riveted and fixed to the tear area.

[0046] The outer side of the pull ring 2 close to the connecting part 21 is set as a support part, which can be against the top surface of the cover body 1. The outer side of the pull ring 2 away from the connecting part 21 is integrally formed with a push part 22 extending outward, and the center line connecting the push part 22 and the connecting part 21 passes through the center of the pull ring 2. Figure 3 As shown, the pull ring 2 is used as a lever, the support part is used as a fulcrum, the push part 22 is used as a power point, F2 is the power, the distance L2 between the push part 22 and the support part is the power arm, the rivet 111 of the connecting part 21 is used as a resistance point, F1 is the resistance, and the distance L1 between the connecting part 21 and the support part is the resistance arm. According to the balance condition of the lever: F2L2=F1L1, the magnitude of the power and the resistance are inversely proportional to the length of the corresponding force arm. Since the center line connecting the push part 22 and the connecting part 21 will pass through the center of the circle of the pull ring 2, it can be known that the power point and the resistance point are distributed on both sides of the center of the circle along the diameter of the pull ring 2, so L2>2L1, in order to meet the lever balance condition, F2<1 / 2F1, when opening the bottle cap, by gently pushing the push part 22, the connecting part 21 can pull up the tearing area under the action of the fulcrum, and then the tearing line 12 near the position of the rivet 111 begins to tear, and opening the bottle cap is more labor-saving.

[0047] Furthermore, the distance between the pushing portion 22 and the supporting portion is equal to five times the distance between the connecting portion 21 and the supporting portion, that is, L2=5L1. To satisfy the lever balance condition, F2=1 / 5F1. Therefore, when opening the bottle cap, only one-fifth of the force needs to be applied to the pushing portion 22, which is more labor-saving.

[0048] The push portion 22 extends beyond the edge of the cover body 1, and the outer side wall of the pull ring 2 integrally extends downward to form a second curved plate 25 except for the push portion 22. The lower end surface of the second curved plate 25 abuts against the top surface of the cover body 1, and the outer side wall of the second curved plate 25 is flush with the side wall of the cover body 1. A clearance gap 23 is formed between the lower side of the push portion 22, the second curved plate 25 and the top surface of the cover body 1, so that when opening the bottle, fingers can be placed in the clearance gap 23 to facilitate lifting or pushing the push portion 22.

[0049] Specific implementation process:

[0050] The cover body 1, the pull ring 2 and the sealing rubber pad 3 are combined into a bottle cap back cover arranged at the bottle mouth, and the edge of the cover body 1 adopts a corrugated edge 13 structure, which presses and fixes the bottle cap at the bottle mouth. When opening the bottle cap, place your fingers in the avoidance gap 23, and bend or push the push part 22 upward, bend or push the pull ring to an inclined or vertical position with the top surface of the cover body, at this time, the tear line 12 near the position of the rivet 111 begins to tear, and after the tear line 12 breaks, pull the pull ring 2 upward, and the tear area continues to tear along the tear line 12. After reaching the end point of the tear line 12, one end of the tear line 12 destroys the edge of the cover body 1, and the bottle cap can be removed, and the other end is still connected to the cover body 1. If the pull ring 2 is continued to be pulled, the cover body 1 and the sealing rubber pad 3 will fall off from the bottle mouth together with the pull ring 2, so as to recycle the waste bottle cap.

[0051] In other embodiments, a beer or beverage easy-pull bottle is also disclosed, and the bottle mouth cover of the bottle in this solution is provided with the above-mentioned beer or beverage easy-pull bottle cover.

[0052] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
